8.4″ ULTRA Resistive Sensor, 5-Wire

8.4″ ULTRA Resistive Sensor, 5-Wire

This is the most durable, economical, and reliable touch sensor available on the market. It has been trusted and widely used for decades.

A D Metro’s advanced, patented design includes a borosilicate glass surface with extreme resistance to scratches, abrasion, and chemicals. The glass surface makes this sensor a suitable component of an IP67 or NEMA 6 enclosure. This sensor has excellent immunity to EMI and compatibility with a wide range of controllers that make it easy to integrate and embed. This sensor is well suited to single-touch applications facing cost constraints, deployed in the most extreme physical environments and likely to face vandalism, abuse or frequent use with sharp objects.

How do Ultra Resistive Touch Screen Sensors Work?

An ULTRA resistive touch screen sensor works in the same way as a resistive touch screen sensor. A resistive touch screen sensor is an analogue switch technology that is pressure activated. Two conductive coated layers (usually using Indium Tin Oxide [ITO]), facing each other, are separated by a layer of dielectric spacer dots. When pressure is applied to the top surface, the two layers come into contact and the controller locates the touch point. To determine the x and y coordinates, in 4- and 8-wire sensors a voltage gradient is applied to each layer in turn; and in 5-wire sensors the resistance is measured between the top layer and each of the four corners of the base layer.

More About Ultra Resistive

ULTRA’s Glass-Film-Glass (GFG) constriction adds a borosilicate glass membrane that enhances the touch screen sensor’s operational life, reduces ITO fracturing and pillowing by creating a stiffer glass/polyester top layer. It also extends the operational temperature range with better matched coefficients of expansion. The glass/polyester top layer does not shatter, or result in spalling, and allows the sensor to continue to operate even after extreme abuse such as deep scoring, repeated impact trauma and other forms of vandalism.
